A biometric access control and time and attendance system comprises an
integrated network including one or more remote access devices in
electronic communication with a computer database. Each remote access
device comprises a silicon chip based system and preferably includes a
biometric input device, a liquid crystal display (LCD), computer
processing capabilities based on embedded system architecture with
configurable system-on-chip (CSOC) technology, and an electrical output
for controlling a door lock or the like. The use of CSOC architecture in
lieu of conventional personal computer technology (e.g. mother boards,
hard drives, video controllers and the like) allows for a more compact
and cost efficient design. A plurality of remote access devices is
configured for communication with a primary computer database wherein
data corresponding to biometric samples for all authorized users is
stored. In an embodiment wherein the biometric input devices comprise
fingerprint scanners, the devices are configured to facilitate
fingerprint identification by incorporating an auto-targeting capability
that enables the user to simply place his or her finger on the
fingerprint scanner whereafter the system adjusts the scanned image by
automatically shifting the scanned image data to a properly targeted
position thereby enabling the system compare the scanned print to the
biometric samples in the system's data storage memory. Auto-targeting
capability eliminates the requirement for manual targeting present in
systems of the background art thereby improving system performance and
minimizing reliance on human interaction. The present invention
contemplates the use of auto-targeting with other biometric systems, such
as facial recognition and/or retinal scanning systems, or any other
biometric identification technology.
